Abstract: FIELD: medicine.  
     SUBSTANCE: invention relates to medicine, namely to pulmonology, and can be used to diagnose a variant of cold hyperreactivity of the respiratory passages in patients with bronchial asthma. To do this, in patients with bronchial asthma with cold hyperreactivity of the respiratory passages, cortisol levels in venous blood are examined, a bronchoprovocation test with isocapnic hyperventilation with cold air is performed. Next, the change in the volume of forced exhalation in 1 second (ΔVFE1) and the instantaneous volume velocity of forced exhalation at the level of 50% of the forced vital capacity of the lungs (ΔIVV50) after a sample of isocapnic hyperventilation with cold air is calculated as % of the initial values. Then the value of the discriminant function D is calculated using the developed equation with the boundary value of the discriminant function equal to -61.12. When the value of D is equal to or greater than the boundary value of the discriminant function, a permanent variant of cold airway hyperreactivity is diagnosed in a patient with bronchial asthma; when the value of D is less than the boundary value of the discriminant function, a fluctuating variant of cold airway hyperreactivity is diagnosed in a patient with bronchial asthma.   
     EFFECT: invention makes it possible to diagnose a permanent or fluctuating variant of cold hyperreactivity of the respiratory tract in this category of patients with a single diagnostic test.

Abstract: A subscriber line access circuit for use in a telecommunications system is disclosed. The subscriber line access circuit has a power supply bridge in the form of a first resistor inserted in the b-wire (ground potential side) of a subscriber line, a second resistor inserted in the a-wire (supply potential side) of the subscriber line, and a capacitor which bridges the two wires at the terminals of the two resistors on the sides thereof opposite to the respective potential sources. This supply bridge is coupled on the capacitor side with a two-to-four wire hybrid transformer for the two-wire/four-wire transition to the system, and includes an evaluating circuit which delivers an indicating signal when the subscriber actuates a ground key. A cutoff circuit is arranged in the power supply bridge in series with the first or the second resistor, or both, between such resistor and the winding of the hybrid transformer to which it, the resistor, as well as the evaluating circuit are connected. This cutoff circuit comprises a cutoff switch which is opened, with a delay, upon ground key actuation and closed when the ground key actuation is terminated.

IPC: G02B6/38
Filed: 1980-07-04
Granted: 1983-01-20
Abstract: The casing (1) has a first through-hole (2) to accommodate the ends of the light guide. A second through-hole (3) is located to one side of the first hole and is connected to it by an angled slot (5). The second hole contains pressure pieces (4). The slot has a blind section (5a,5b) curling around the first hole. The casing may contain several first holes all sharing one second hole and connected to it by several slots. The slots are made by electro-erosion using a wire drawn through the solid casing or they are made by dissolving parts of the casing by electrochemical means. The slot or slots give the casing the elasticity needed for clamping the light guide in the first hole. The pressure pieces expand the second hole thereby pressing the part of the casing delineated by the slot against the light guide in the first hole. The advantage lies in reduced fabrication costs.

Granted: 1986-03-20
Abstract: Es werden ein Verfahren und eine Schaltung für eine Abtaststeuerung zur Aufrechterhaltung eines konstanten überstrichenen Frequenzbereichs eines spannungsgesteuerten Oszillators (VCO) beim Umschalten zwischen linearer und nichtlinearer Abtastfunktion bereitgestellt. Die Abtaststeuerschaltung enthält einen linearen und einen exponentiellen Verstärker, deren jeder ein Ausgangsspannungsfenster aufweist, das im linearen Dynamikbereich des VCO angepaßt ist. Unabhängig voneinander ausgewählte Start- und Stopspannungen sind über den gesamten linearen Bereich des VCO zur Festlegung der oberen und unteren Frequenzgrenzen einstellbar, je nach Wunsch für lineare oder logarithmische Abtastung. Logarithmische Konverter werden zur Anpassung der linearen Start- und Stopspannung an ihre logarithmischen Entsprechungen verwendet, so daß die VCO-Frequenz beim Umschalten von einer Funktion auf die andere nicht verschoben wird. Dies erlaubt die Verwendung einer einzigen Startfrequenz und einer einzigen Stopfrequenzsteuerung. Eine Rampenspannung, die entsprechend der linearen und logarithmischen Funktion skaliert ist, wird zur Abtastung des VCO angelegt. Während die Übertragungsfunktionen der logarithmischen Konverter und des exponentiellen Verstärkers stark temperaturabhängig sind, ist die Topologie so ausgelegt, daß bei der Berechnung der Gesamtübertragungsfunktion die Temperaturterme herausfallen.
